Since there is so much variance in the data, it seemed good way to study it was to look at the total timing advance during a run. So here are two comparable runs (cropped so min and max RPM recorded match up), with the only difference between them being 100% offset vs. 0% offset. If the format works I can add the other runs in for master averages, these just happen to be the first run of batch each I picked. Like I said earlier all of the runs are all over the place which may just be due to the 91 octane and Stage 3 boost levels, but the averages should give us a good picture of what is really going on.

Anyway the net result is that 0% CPS offset resulted in 3.43 degrees average timing advance, while 100% CPS offset resulted in 3.49 degrees average timing advance. Hardly any difference at all.
